Abstract: 793,329. Aircraft undercarriages. SOC. D' INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. Jan. 23, 1956 [Jan. 22, 1955], No. 2217/56. Class 4. An aircraft undercarriage having a leg 1 pivoted at I to the airframe is braced by a backstay 4 and retracted by a jack 5. The backstay is pivoted to the airframe at II and at V to the leg 1, this latter pivot being located at the lower extremity of a crank-arm 3 pivoted at IV to the leg. The crank-arm is hollow to enclose a plunger 6, the lower end 8 of which is urged into locking engagement with a recess 9 formed as an extension of the leg 1. An arm 10, pivoted at VI to the crank-arm 3, carries a finger 11 which engages a recess 12 in plunger 6, an extension for engaging a stop 14 on arm 3 and a pivot VII for attachment to the piston rod of jack 5. The other end of the jack is connected at III to the stay 4. With the apparatus in the position shown in Fig. 2, the undercarriage is locked in its extended position. Extension of jack 5 for retraction first rocks arm 10 to cause finger 11 to withdraw plunger 6 from locking engagement with recess 9 until the arm 10 bears on a stop 13, subsequent extension of the jack forcing arm 3 and leg 1 upwardly to the position shown in Fig. 3 wherein the pivots II, V arid IV are in alignment, thereby locking the undercarriage in its raised position. The undercarriage is lowered by reverse movement of the jack but in a further embodiment, not shown, the said pivots are not in alignment so that the undercarriage may descend under the action of its own weight.

Patent GB-693717-A (GB)
Title: Film casting surfaces
IPC: B29C41/24
Filed: 1951-01-30
Abstract: A film-casting support is provided with a film-casting surface by forming a coating of a cellulose derivative on the support and chemically altering the surface of the coating by applying a suitable reagent in a dope containing a film-forming material, which is unaffected by the reagent, so as to form a temporary film over the surface, and then removing the temporary film from the surface after the reaction has proceeded to the desired extent. The cellulose derivative may be a water-insoluble saponifiable ester and the reagent may be a saponifying agent, e.g. sodium or potassium hydroxide or carbonate, sodium or potassium alcoholate, methylamine, ethylene diamine, benzylamine or a quaternary ammonium base.  The film-forming substance in the dope containing the chemical reagent may be methyl, ethyl or carboxymethyl cellulose or an alkali-soluble copolymer of styrene.  The solvent used in the dope containing the reagent may have a swelling action on the cellulose derivative of the coating on the support.  A film-casting drum or belt may be coated with a cellulose ester and the surface of this coating may be saponified by the process described.  The cellulose ester may be cellulose acetate, propionate, butyrate, or aceto-butyrate.  The operations of applying the dope containing the chemical reagent, setting and drying the applied layer, and stripping when the reaction has proceeded to the desired extent, may be carried out as a continuous process.  In an example, a casting drum is coated with a thin layer of cellulose acetate which is soluble in methoxyethyl acetate.  On this coating there are cast several superimposed layers of a dope containing ethyl cellulose and 0.6 per cent of potassium hydroxide in methanol.  After drying, the ethyl cellulose film is stripped from the drum, leaving a coating of cellulose acetate which has been saponified in the surface layer.
